PAPER nEFLncroit Application filed December 22, 1924. Serial No,757,357.

My invention relates to improvements in paper deflectors and has for itsobject the provision of means in association, preferably, withcontinuous sheet-feeding mechanism whereby the sheets of paper will besupplied to the conveyor or travelingbelt in evenly displaced orfanned-out arrangement for presentation to the feeding rolls.

Continuous feeding mechanism of the type to which may improvements areherein applied affords two levels, usually comprising feeding beltstraveling over feedlng tables arranged one above the other, whereon saidbelts travel in reverse direction. The upper level or table is suppliedby the attendant with the sheets of paper fanned-out from the bottom tothe top and suitable deflector means are provided for turning the paperfanned out in reverse arrangement and for positioning the paper upon thelower table.

Hitherto the reversing means has comprised a third set of travelingbelts, but considerable difiiculty has been met with 111 the operationof sheet deflectors thus equipped, for the reason that the outermostsheets would be advanced at a different rate of speed than would theinnermost sheets, thereby disarranging the fanned-out positioning or relation of the sheets when reversely disposed upon the lower feed table.Obviously this slows down and interferes with the opera tion of theassociated paper-feeding and handling mechanism.

Accordingly, I have substituted, with distinct attendant advantages, forthe reversing set of webs or belts employed in the prior art, a set ofcurved resilient members adapted to be adjusted into positions fordeflecting the sheets and reversing them in their passage or transferfrom one level of the machine to the other. Moreover, I may associatewith'said means a second adjustable deflector so that the sheets are notdisarranged and are delivered in reversely fannedout arrangement to thelower feeding table.

The -features of my improved construc tion may be more readily explainedin connection with the accompanying drawings illustrating a preferredembodiment thereof, wherein: V

Figure 1 is a side view of a two-level continuous sheet-feedingmechanism to which my improvements have been adapted and applied,

Fig. 2 is an interrupted plan view thereof on the irregular line 2-2,Fig. 1,

Fig. 3 is an enlarged fragmentary view in vertical section illustratingthe sheet deflector upon an enlarged scale with a pile of fanned-outsheets in transit therethrough, and

Fig. 4 is a similar View thereof showing the pile of fanned-out sheetsabout to be entered within said deflector.

Throughout the several figures of the drawings I have employed the samecharacter of reference to indicate similar parts.

. Making initial reference to Figures 1 and 2, it will be seen thatthesheet-feeding mechanism comprises an upper feeding table asuperposed ata slight angle above the lower feeding table (1; said feeding tablesrespectively being equipped with sets of traveling belts a, b, whereonthe sheets are conveyed in reverse directions. Lateral guides a", b" areadjustably mounted in position to direct the sheets in alinement towardthe deflector mechanism upon the right of the machine, and again, towardthe feeding rolls upon the left of the construction shown.

It may be observed at this point that preferably the sheets are suppliedto the continuous feeding appliance in a substantially continuous oruninterrupted thickness of superposed fanned-out sheets of paperextending from a position rearwardly or to the left of the deflectormechanism and along the lower feeding table to the feeding rolls 0, 0'at the left. However, for the purpose of illustration and description Ihave shown merely two bundles or sections of sheets (I, d, suitablyfanned-out respectively upon the upper and lower feeding tables. Theformer is manually disposed upon the table a and properly fanned-out bythe operative for passing through the deflector mechanisnn'as indicatedin Fig. 3, while the latter section exhibits the reverse arrangement ofthe sheets after passing through the deflector, adapting them for theaction of the feeding rolls. In this arrangement the forward edges ofthe sheets overlie and extend beyond the forward edges of those beneaththem in the particular group or section, and, in practice, this'mode ofsuperposition is maintained as :nearly continuous as possible in orderto expedite operations and production.

The particular mechanism for eflecting the deflectionand reversal of thesheet arrangement may now be explained by making reference to Fi ures 3and 4; in the latter .of which the etiges of the fanned-out sheets (Iare shown forwardly advancing beneath the curved resilient members ethat are adjustably mounted alon the rod e to conform with theparticular wi th of paper in progress or transit through the deflector,and, generally, with the contour of the preferred thickness of thesection of sheets as it passes around the cylinder f of the deflector,as shown in Fig. 3. Each of the resilient members is adjustably held inposition upon and about the rod e by its thumb-screw e Beneath saidcylinder there are also provided 'a series of guides or deflector shoes9 adjustably mounted uponthe rod 9' forthe purpose of directing thereversed sheets when released from the members e, upon the travelinbelts VI) of the lower feeding table, along-an with which said sheetsare conveyed toward and between the feeding rolls 0, c, for transfer tofolding or other apparatus for perfectin the sheets, not shown herein.The details 0 the 'auxiliarymechanism do not require further descriptionor illustration to make clear the construction. and purpose of thepresent improvements. k

It will be-Observed that the terminals of the member's eare hooked ate", so that with .an excessive thickness of paper, or with paper ofunusual stiffness, the forward edges will be directed invariably againstthe righthand portions o'ftthe adjustable shoes 9. This is insuredthrough the enga ement, when nec- Tessary, of tlie hooked en s with therod 72.

above indicated. a

From the foregoing it will be seen that the acting as a limit member orstop for the purapparatus of my present invention is of extremely simplecharact'er, yet it"adrnirably. meets theiurposein hand and overcomeseerparatus of the prior art..
